Cinema For decades, the same scene has been used to film a teacher or a middle-aged office clerk. The teacher is busy writing something in a notebook or register while wearing glasses. At that very moment, a child comes and asks him to do something. The teacher’s eyes peek over the glasses and look at the child. Have you ever wondered why the teacher looked at the child over the glasses?
This happens due to an eye condition called presbyopia. In this, the near vision becomes weak. The teacher is wearing glasses for its correction. These glasses are necessary for looking at a book or notebook, but to see distant objects, those glasses have to be removed.
Presbyopia is an age-related problem, which usually occurs after the age of 40. This problem occurs when the elasticity of the lens of our eyes decreases. Options like glasses, contact lenses and surgery are already available to correct it. Now for some time now, there has been a discussion in India about eye drops Presvue as an option for its treatment.
Today ‘health report‘ I will talk about presbyopia. Along with that, we will know that-
- What do the statistics on presbyopia in India and around the world say?
- What are its symptoms?
- What are its risk factors?
- What kind of lifestyle can prevent presbyopia?
what is presbyopia
The special thing about our eyes is that its focus changes according to the distance we see or read. This means that the lens of the eyes is elastic. In case of presbyopia, the ability of the eyes to change focus is lost. Due to this, near vision becomes weak and problems arise in reading and writing.
Presbyopia in the country and the world
According to a study published in the National Library of Medicine, 1.8 billion people worldwide are affected by presbyopia. This figure is quite large in India too. Let’s see in the graphic.
The market for correction of presbyopia eye condition is growing
Data Bridge Market Research released data related to presbyopia in the year 2021. It was told that people around the world spend 944.1 crore US dollars on examination, correction, lenses and medicines for eyes affected by presbyopia. It has also been estimated that this expenditure is going to increase at a compound growth rate of 4.90% in the next seven years. This means that at the speed at which the cases of presbyopia are increasing, by the year 2029, people all over the world will be spending 1384 crore US dollars for it.
What are the symptoms of presbyopia
The most common symptoms of presbyopia appear in most people around the age of 40. Due to this, there is a gradual decline in the ability to read or do close work. What are its other symptoms, see the graphic.
A natural camera is fitted in our eyes
Our eyes are like a camera. To take a picture with a camera, the lens has to be changed for near and far objects, whereas the lens of our eyes has the ability to autofocus.
As we age, the lens of the eye gradually loses its elasticity. Therefore, due to presbyopia, we face difficulty in focusing. Usually, this problem starts after the age of 40. However, sometimes premature presbyopia can also occur due to poor lifestyle.
What are the risk factors for premature presbyopia
Its main risk factor is being over 40 years of age. However, due to dangerous lifestyle, some medicines and medical conditions, this condition can develop even under the age of 40. This is called premature presbyopia.
Diseases like anemia, heart diseases and diabetes are the major risk factors. Apart from this, medicines for depression, allergy and mental disorders can also cause premature presbyopia.
Let’s see the graphic.
How presbyopia is corrected
There is no cure for presbyopia. However, some treatments are available to improve vision. This condition is treated based on a person’s health, lifestyle and preferences. The following are the methods for its correction.
- Wear glasses of correct power.
- Wearing contact lenses in the eyes.
- By doing eye surgery.
- With the help of eye drops.
How to prevent premature presbyopia
Presbyopia is not a disease. It is a condition that develops with age. Therefore, there is no sure way to prevent it. With time, the ability to see nearby objects keeps getting weaker.
However, efforts can definitely be made to prevent premature presbyopia. For this, follow a good lifestyle. Eat nutritious food and get your eyes checked regularly. If you go out in the sun, wear sunglasses to avoid harmful ultraviolet rays. Eat foods rich in nutrients necessary for eye health including vitamin A, vitamin C, vitamin E and lutein. For this, carrots, spinach, tomatoes, oranges and green vegetables should be eaten.
